A trumpet interchange allowed consolidating the toll gates into one point at each interchange.

Exactly. On a ticket system this is the most cost-effective way of handling things.

Not to mention it was the best way to prevent most "illegal" mainline U-turns

Regarding this new roundabout on 53, it's worth noting that 53 was a 4 lane road through the trumpet but narrowed down to 2 lanes immediately north of it.

I haven't seen the new configuration yet, but I'm guessing they didn't do a 2 lane roundabout and instead dropped 53 from 4 lanes to 2 lanes somewhere between Schwartz Dr. and this new roundabout.

Why were so many toll road interchanges built as trumpet interchanges on both ends? Wouldn't standard diamond interchanges have sufficed? Seems like a waste of land to me.

Agreed. Time to fix the old substandard turnpike highways with all those trumpet interchanges.

There's nothing inherently substandard or wrong about a trumpet interchange. If it ain't broke, don't waste tollpayer money fixing it.

Trumpet interchanges like that actually may have benefits beyond the toll booth itself. By consolidating traffic to only one intersection, it can reduce congestion on the cross street caused by two signals being too close to each other. It also makes finding the on ramp easier, since there's only one and then you can decide which way.

I've built a handful of these on Cities: Skylines for this reason, and also since nowadays toll booths are available in game.

And remember, everything "old" is fine if the volume is low enough.

The more recent Turnpike interchanges in western Ohio were built from scratch with intersections instead of trumpets like they would have been if they were original to the road, probably because of the low-enough volume and it being cheaper.  I always found interesting that the signs at the intersection (both directing traffic to the Turnpike as well as the directional signs at the intersection for exiting traffic) were button copy which was not the Turnpike's thing.  They must have had ODOT do those signs as they were on an ODOT road (just as on freeways the exit signs for the Turnpike exit are regular ODOT signs, with Turnpike-designed signs not appearing until on their property). Some of the latest button copy installed in Ohio still remains in locations like that (e.g., the OH 66 interchange opened in 1998 and has button copy signs at the intersection) and they still look good even at night. 

Until the bridges serving trumpets on low-volume interchanges reach the end of their service life, it doesn't make sense to replace them just because they are there "needlessly".  Building them originally was good future-proofing and when they run out of life, then alternatives make sense to consider.

It wasn't until I lived in Toledo in my college years that I discovered that there was one original turnpike exit on the Ohio Turnpike that did NOT have a trumpet interchange beyond the toll booth...Exit 34/Old Exit 3 in Wauseon, which was more or less a T intersection with SR-108.

And then I was surprised when I saw T-intersections at some of the New York Thruway exits, I guess I thought all Toll Roads were required to have Trumpet interchanges when I was a kid.

Just goes to show how few exits the Turnpike had initially that Exit 34 was old Exit 3. That is a very long way between exits for Ohio. There's a sign on I-70 west near Zanesville that warns you that it is a whole nine miles to the next exit.

Originally it was only 16 exits, now it's up to 30.

Note: may have been a few more than 16 originally, I'm not quite sure if the partial exits for I-90, I-480 and I-680 with old numbers 8A, 9A and 16A were original exits that were given letters because they were partial exits, or if they came latter like all the other A and B exits that were added between the original construction and the switch to mileage based exit numbers.

The Turnpike was built in the mid-1950s. Those partial exits were later additions.

IIRC, the addition of new exits was a key reason why the Turnpike switched to mileage-based exit numbers in the late 90s/early 00s.

I want to say the first "new" exit that was built was a little over 20 years after the Turnpike opened -- and IIRC, it was Exit 8-A, the connector to SR-2 (and later I-90 once it was fully completed into downtown Cleveland).  I-680 and the I-480 partial exits came soon after.

As time passes, those older interchanges that had trumpet ramps and single ticket/cash tollgates for traffic getting on and off of the highway can be replaced with more conventional diamond, par-clo and other needed connections with transponder gantries, including at newly added local access interchanges, as needed.

There's a sign on I-70 west near Zanesville that warns you that it is a whole nine miles to the next exit.

And yet there's no such warning for the 14 mile gap on I-71 between SR 95 and SR 97

[GCrites80s]

Different District?

[Buck87]

Different District?

Yes.

The Zanesville area example is entirely in District 5

The OH 95 end of I-71's 14 mile stretch is in District 6, while the OH 97 end is in District 3.

I couldn't figure out how to get Google Maps to show counties today.

Much less the 12 miles between I-270 & 36/37 back in the day (Pre Polaris)

It doesn't.  Third parties have added the layer (e.g. at mob-rule.com).

If you search for a specific county, it will outline that county but the outline goes away as you zoom in close.

Ah, true.  It's functionality is so limited, I dismissed it out of hand.

One of the most welcome new interchanges was Exit 52, for SR-2 and the Toledo Express Airport (TOL).  It was built with an intersection, complete with a 4th movement leading right into the airport.  Now if it were a major airport, an overpass and interchange with SR-2 would be a given.  But TOL is currently served by only TWO airlines, having long since been eclipsed by Detroit Metro (DTW), which the construction of I-275 made it easier for Toledoans to get to.  Even with the Turnpike exit, access to TOL is still a little roundabout; see this post for details.
